Anyone to the London's Brazilian carnival?4-5March

I am from Internations in Bern, Switzerland, and was wondering if any of you would go to a Brazilian carnival during the 1st week-end of March, which is when we, Brazilian, we celebrate carnival. I'm far from being a carnaval party goer, but I live in a very sleepy town - Bern... and 3 years without the sound of samba is way too much...

So, I'll be in London on those dates. I checked the net and found the Guanabara carnival Protected content . Any other suggestions are welcome. Would be nice to gather a small group.
